Inspect EC50 fit quality and failures — fit

`fit_quality()` returns group-level quality information for successful fits. `fit_failures()` returns failed group/model combinations as data.

Usage

fit_quality(x)

fit_failures(x)

Arguments

x: An object returned by [estimate_EC50()] or [ec50_multimodel()].

Value

A data frame.

Examples

data(multi_isolate)
fit <- estimate_EC50(
  growth ~ dose,
  data = subset(multi_isolate, isolate %in% 1:3 & fungicida == "Fungicide A"),
  isolate_col = "isolate",
  strata_col = "field",
  fct = drc::LL.3()
)
